本文将为您介绍PolarDB PostgreSQL版(兼容Oracle)错误码。

错误码格式

本数据库服务器发出的所有消息都被赋予了五个字符错误码,这遵循 SQL 标准对“SQLSTATE”代码的习惯。需要知道发生了什么错误条件的应用通常应该测试错误码, 而不是查看文本形式的错误消息。这些错误码轻易不会在本数据库的版本之间改变,并且一般也不会随着错误消息的本地化而改变。请注意有些(但不是全部)本数据库生成的错误码是由 SQL 标准定义的;有些标准没有定义的额外错误码是本数据库发明的或者是从其它数据库借用的。

根据标准,错误码的前两个字符表示错误类别,而后三个字符表示在该类别内的一种特定情况。因此, 那些不能识别特定错误码的应用仍然可以从错误类别中推断要做什么。

表 1 中列出了本数据库定义的所有错误码(有些实际上目前并没有使用,但是 SQL 标准中有定义)。错误类别也在其中列出。对于每个错误类别都有一个 “标准”错误码,它的最后三个字符是000。这个代码只用于那些属于该类别但是没有被赋予更特定代码的错误情况。

“情况名称”列中显示的符号是在PL/SQL中使用的情况名称。情况名称可以被写成大写或小写形式(注意PL/SQL不识别警告(与错误不同)情况名称,它们是类别 00、01 和 02)。

对于某些类型的错误,服务器会报告与错误相关的数据库对象(一个表、表列、数据类型或约束)的名称。例如,导致一个unique_violation错误的唯一约束的名称。这些名字被包含在错误报告消息的独立域中,这样应用就不必从可能是本地化的人类可读的消息文本中抽取它们。
